I rarely do this, but I feel the need to examine these stories individually before I comment on the book as a whole. Pay attention:
Making Amends - 8 pages - solid, but nothing amazing.
Pariah - 5 pages - kind of cute, but not really the reason I read zombie comics. This would have fit perfectly in a different collection, and been quite enjoyable.
In Sickness - 8 pages - subtle, sneak-up-on-you stuff. Quite good.
Necrotic - 64 pages (!) - here is where the trouble really starts. This is the second longest story, and it suffers from some severe problems. First, there's no zombies in this story, so it's inclusion seems a little weird. I mean, there's a mummy...sort of. There's really just a guy who figures out how to get mummy powers, or something. I don't know. But it shouldn't have been in this book. Second, near the finale, the pages are significantly OUT OF ORDER. And I don't mean they're irreverent or that they interrupt, I mean you can't figure out wtf is going on, because they're LITERALLY out of order. In case you can get past those two problems, there's another significant problem, which is that this story is just terrible. Lame in every way--totally mediocre art, and written by what I can only assume is a 9th grader. Why is this in this book? (And notice it's one of the long ones--that bumps up the page count. We gotta be "Mammoth," you know.)
The Immortals - 6 pages - This one is good, but if you read much, you've probably seen it in a Negative Burn anthology.
Flight From Earth - 12 pages - pretty juvenile all around.
Amy - 16 pages - There are zombies here, but there's also some sort of ghost (or maybe a will-o-wisp...some glowy ball, anyway.) I could never figure out what really happened in this one, so....meh.
Black Sabbath - 8 pages - dumb.
MAZH - 10 pages - The editor apparently decided this story should be called MASH, even though it's clearly MAZH in the comic itself. I can't figure that out; single-letter-momentary-dyslexia, maybe? Japanese-style art, which I don't like (although some people do.) But is there a zombie in this story? I see a Frankenstein-type character, but no zombie.. There is a panel where...something happens...maybe that person is a zombie?
Dead Eyes Open - 142 pages - This story basically saves this book from being 1 star. This is a very non-classical zombie story, where the zombies retain their memories when they turn. It's an exploration of the societal changes which would occur in such a situation. This story I would give a 4/5. It's not perfect, but it is very interesting. It seems like manna from heaven compared to most of the garbage in this book.
Might of the Living Dead - 6 pages - A funny look at the history and significance of zombies. The phrase "amphetamine-fuelled long distance runners" will enter my vocabulary.
Job Satisfaction - 4 pages - A vignette. Not bad, but doesn't really offer anything.
The Corpse / The Haunted Ship / The Zombie - All by the same artist. These all have that folk tale feel, like a sort of unsatisfactory ending and some weird twists. I didn't love any of them, but I enjoyed them all.
Pigeons From Hell - 51 pages - Apparently based on some classic horror story (which I will soon read), this was the creepiest thing in the book, but suffers from two main problems: the wordless storytelling made it impossible to tell exactly what happens. My wife and I both read it twice, and couldn't quite make sense of it. Also, I don't know how the original looks, but this printing is dark to the point of eyestrain. It looks good, but a bit more contrast would have been nice. Also, is there a zombie in this story?
Zombie World: Dead End - 44 pages - A nice horror / zombie story that goes somewhere unexpected. I liked this one.
"Zombies" - 6 pages - 5/5. This is pretty much what every short piece in this book should have been. Solid art, a nice theme, and solidly creepy.
So here's the summary. If I were picking zombie stories for inclusion in an anthology of "zombie comics," 4 of these stories would have been excluded because they don't (or don't obviously) have zombies in them, and really only 8 of the 18 would have been even in the running, on quality grounds. Probably 3 would have made it. An incredible amount of material in this book is just bad or irrelevant.
Also, note: The first half of the book mostly sucks. The good stuff is near the end. Why in the world would the editor order things that way? Shouldn't you put the good stuff in the front?
